CLI: Zowe Clients Event Management

[zFernand0]

ℹ️ This is different from the Event Management effort on z/OS ℹ️

The idea is to allow for multiple applications to be notified when certain client events occur. Here are some of the events we have identified so far:

• onVaultChanged: When an SDK writes to the vault / credential-manager (i.e. password update)
• onConfigChanged: When a Team Config file changes (i.e. new properties stored)
• onSchemaChanged: When the schema file changes (i.e. new plug-in or extension installed)

We will also allow for custom events. The following is just an example:

• onPackagePublished: This is an example of an event that a plug-in or extension could emit if they just published a package

The CLI squad has been investigating this for the Node.JS SDK. We are in the process producing guidelines that every SDK could implement (Python, Kotlin, Java, Swift, ...)
